24 Claims.

The present invention relates to printing telegraph apparatus and moreparticularly to improvements in tabulating mechanisms therefor.

It is the principal object of this invention to provide an efficient andsmoothly operating tabulating mechanism selectively responsive to codecombinations of signalling impulses for controlling tabulationrecording.

A feature of the invention resides in enhancing the speed of movement ofthe type carriage in effecting the tabulating function, during whichoperation the type carriage will be spaced continuously at a speed whichis three times that of normal spacing.

The above and other objects of the present invention are accomplished bythe provision in a printing telegraph apparatus of a tabulator bar whichextends across the front of the machine and is pivotally carried bybrackets and capable of swinging toward and away from the type carriage.The tabulator bar carries a number of adjustable stop members whichdetermine the positions at which the type carriage comes to rest afterspacing during the tabulating cycle. The spacing mechanism oftheprintingapparatus comprises a three-toothed ratchet adapted tocooperate with a pair of pawls which are actuated by the printing bailto function as an escapement mechanism so that, upon each revolution 30of the main shaft, the spacing worm gear associated with the spacingratchet is permitted to rotate one-third of a revolution.

A series of function levers is provided which operate selectively inaccordance with the setting of a series of selector vanes. Among thefunction levers of this series is a tabulating function lever which,when selected, is drawn forward under spring tension. When this occurs,the rear extension of the function lever rises and thereby lifts therear end of a horizontal member. When the rear end of this horizontalmember is lifted, it lifts the upper space pawl out of engagement withthe tooth of the spacing ratchet, atWhich time the front end of saidhorizontal member is lowered thereby unlatching the tabulating bar topermit the latter to be rotated by its spring toward the type carriage.When the upper space pawl is thus disengaged, the lower space pawlremains in its normal position entirely free of so the teeth on theescapement ratchet, thus permitting the spacing worm gear to make onecomplete revolution instead of only one-third of a revolution during thetime that the main shaft rotates through one revolution, and thereforethe 1a carriage will be spaced continuously a distance per revolution ofthe main shaft which is three times that of normal spacing distance. Tobring the carriage to rest after tabulating it is necessary to permitthe upper space pawl to drop again into engagement with a tooth on thespacing ratchet. This latter function is effected by the cooperation ofa cam element assembled to the carriage and one of the adjustable stopmembers carried by the tabulator bar. This cam. forces or cams thetabulator bar forward or away from the carriage, against spring tension,and in doing so permits said horizontal member to be restored to itsnormal position into latching engagement with the tabulator bar. Thisrestoration action of the horizontal member permits the upper space pawlagain to fall into engagement with a tooth on the spacing worm ratchet,which thereupon brings the carriage to rest.

In the accompanying drawings like reference characters indicate similarparts throughout. For a complete understanding of details not disclosedherein and which form no part of the present invention, reference may behad to the U. S. Patent No. 1,904,164 issued April 18, 1933 to S. Mortonet a1.

Briefly, having reference to Figs. 1, 3, and 6, a printing apparatus towhich the tabulating mechanism of the present invention is appliedcomprises a typing unit (shown generaly in section in Fig. 3) whichincludes a primary selecting mechanism indicated generally as ll (Fig.6) which is of the sword-and-T type disclosed in U. S. Patent No.1,745,633 to S. Morton et al. (fully disclosed in the first mentionedpatent), and a. secondary selector or selector vane assembly indicatedgenerally as Ill. The selector vane assembly l2 controls through aseries of bell cranks l3 (Fig. l) a corresponding series of curved codebars 4 carried in a movable type carriage. As set forth in the firstmentioned patent, this type carriage, indicated generally as I5, ismovable longitudinally in respect to a stationary platen indicatedgenerally as I6 (Fig. 3). The type carriage |5 also carries a ribbonfeed mechanism indicated generally as H.

Referring particularly to Fig. 6, a motor I8 supplies power through gearI!) to a main operating shaft 2| which carries the spacing mechanismindicated generally as 22 and the selector cam assembly indicatedgenerally as 23. As is known in this type of device, power iscommunicated from the motor to an operating cam assembly through a grabclutch such as 25. Pinned portion 24 of grab clutch 25 constantlyrotates with the shaft 2|, which has also frictionally connected theretothe spacing mechanism 22 and the selecting cam assembly 23. Portion 24is cooperatively engaged with the splined portion 26 when throw-outlever 21 is operated in timed relation with the reception of codesignals.

The spacing mechanism 22, which will be described more in detailhereinafter, controls through gear 28, shaft 29, gear 3|, and rack 32(Fig. 3), the movement of type carriage |5 to form character spaces,tending in this movement to wind up the carriage return spring mechanismindicated generally as 33. Upon receipt of the carriage return signal,function bar 34 is actuated selectively in the manner described inPatent No. 1,904,164 so as to permit spring 35 to rotate lever 36suddenly against stop 31 to raise, through bell crank 38, portion 39 ofgrab clutch 4|. Carriage return mechanism 33 is thereupon permitted, dueto the energy stored up therein, to return the carriage |5 to its normalor beginning-of-line position.

Positioned parallel to the main operating shaft 2| is a rocking shaft 42on which are carried various mechanisms, for, example, printing bail 43,function bail 40 and the escapement mechanism for the spacing mechanism22. The printing bail 43, which is actuated by a printing spring (notshown) in proper timed relation in the operative cycle, functions toreciprocate a pull bar operating member 44 to cause the operation of atype bar, as clearly described in the aforementioned patent.

The selector vanes as set forth in Patent No. 1,904,164 control a seriesof function levers among which are provided especially for accomplishingthe object of the present invention is a tabulating function lever 45which like the other function levers is pivoted on a common pivot rod 46and is assembled in a slot in the function lever comb 41. This functionlever 45, like the rest of the function levers of the series, isprovided with an individual spring 48 tensioned between it and theprinter frame which tends to rotate the function lever 45 about pivot 46but, as clearly set forth in Patent No. 1,904,164, is restrained by thefunction lever bail 40 acting through rod 50 on arm 60.

Before describing further the function of lever 45, a detaileddescription of the spacing mechanism will be given. Having reference toFigs. 3 and 5 there is shown mounted on the main shaft 2| and locatedcentrally of the apparatus a sleeve member 5| which comprises escapementratchet 52 and escapement worm 53 which are integral therewith. Sleevemember 5| is operably connected to the hub of a disc 54 by means ofinterengaging tongue and groove members 55. Collar 56 is pinned to mainshaft 2| and is rotatable therewith. Interposed between disc 54 andcollar 56 is disc 51 of frictional material, for example, felt. By meansof a helical compression spring 58, which exerts a thrust tensionbetween disc 51 and a pinned collar sleeve 5| is frictionally connectedto shaft 2| through the friction clutch comprising members 54, 56, and51. Sleeve 5| is thereby rotatable with main shaft 2| unless arrested bythe escapement pawls of the spacing mechanism 22 as will presentlyappear.

Referring to Fig. 3 it will be noted that ratchet 52 is provided withthree teeth or notches 6|, 6|a, and 6H), the escapement of which willallow the type carriage 5 to be moved forward one step or characterspace for each actuation of the printing bail 43. As indicated, theescapement mechanism comprises levers 62 and 63, pivotally mounted onbail shaft 42, and lever 64 adjustably fixed to printing bail 43. Spring65 normally tends to rotate levers 62 and 63 in opposite directions,since it is common to both levers. Lever 62 is normally urged by spring65 in a counterclockwise direction so that laterally disposed end 66engages tooth 6| of ratchet 52, thus arresting the rotation of saidratchet. Lever 63 is normally held out of engagement with ratchet 52against the tension of spring 65 by the action of lever 64 againstlaterally disposed end 61.

Lever 64 is pivotally connected to printing bail 43 at 68 and isprovided at 69 with a slot and screw adjusting means, whereby thecorrect rela tive position of escapement levers 62 and 63 with respectto ratchet 52 may be determined. The spacing operation occursimmediately following or subsequent to the printing of a character inthe following manner.

Upon the printing of a character, lever 64 is caused to rotate slightlyin a clockwise direction with printing bail 43 which moves clockwiseabout the axis of bail shaft 42, thereby transferring this motion tolever 62 through its laterally disposed end 1|, tripping its end 66 outof engagement with tooth 6| and permitting ratchet 52 to rotate slightlyin a clockwise direction under the influence of friction clutch members54 to 51 (Fig. 5) until arrested by the engagement of tooth 6|a withlaterally disposed end 12 of lever 63 which lever by movement of lever64 was rendered free to rotate in a clockwise direction under thetension of spring 65 into the path of oncoming tooth 6|a. Ratchet 52 isthus restrained from rotation by lever 63 until the completion of theprinting of a character at which time printing direction due to theaction of lever 64 on end- 61 thereof, thereby disengaging end 12 oflever 63 from tooth 6|a and allowing ratchet 52 to continue its rotationuntil arrested by the engagement of end 66 of lever 62 with tooth Gib.

It is obvious that since worm 53 and ratchet 52 are integrally connectedto sleeve 5|, said Worm 53 will have normally the same intermittent orstep-by-step motion as was hereinbefore seen to be imparted to ratchet52. Worm 53 is meshed with worm gear 28 (Figs. 3 and 6) which is looselymounted on vertical shaft 29, and is operably connected thereto by meansof jaw clutch 4i. Worm 53 and gear 28 are so related that one-third 5revolution of worm 53 will rotate gear 28 through a distance which,through gear 3i and rack 32, causes the type carriage to be steppedforward one character space.

From the foregoing it will be observed that character spacing takesplace automatically with the printing of each character; that is, thespacing function is merged into the printing operation. It is well knownthat there is a code combination allotted to each type bar; but it ispossible, 5 however, to employ a code combination, common ly known asthe spacing signal, which is identified with no type bar but which willnevertheless initiate the printing operation. Therefore the spacingbetween words is accomplished in exactly the same manner as' set forthwhen a spacing signal is received, except that no type bar is operatedand consequently no character is printed.

In accordance with the present invention, continuous spacing may beeffected upon the receipt of a code combination known as the tabulatingcode combination which functions to initiate the operation of thetabulating mechanism.

The mechanically operated tabulating arrangement of the presentinvention comprises a tabulator bar 98 extending across the front of theprinting apparatus, as shown in Fig. 1, which is provided with dependingportions 92 and 83 through which bar 8! is pivotally mounted on bracket94 carried in the printer frame. Thus tabulator bar 9i is adapted to beswingable toward and away from the type carriage 15. Bar ti is alsoprovided with a longitudinal slot 85 extending substantially the entirelength of the bar. In this slot are adjustably movable stop members 85which are adapted to be clamped to the bar ti by means of screws 81 andclamps 528 individual to each stop member 85 (Fig. 3). As indicated inFig. 6, these stop members 85 are each provided with an inclined or camportion 39, specially conformed so as to provide a quick action uponcooperation with a cam element till carried by the type carriage, toterminate suddenly the tabulating operation. 7

Tabulator bar Si is also provided, intermediate the depending portions82 and 99 (Fig. 1) and suitably positioned relative to function lever55, with another depending portion 9i. Attached to and depending fromportion 9i is a bar 92 the lower end of which is provided with anaperture 99 having its upper left-hand corner (as viewed in Fig. 3)conformed so as to provide a reentrant stepped portion 94. The tabulatorbar M, as indicated in Fig. 6, normally tends to move toward theprinting apparatus due to the action of a spring 95.

Cooperating with the stepped portion 95 is one arm 96 of a lever 91pivotally carried at 99 on a support 99 secured to the function levercomb 41. The extremity of arm 96 is provided with a 63 laterallydisposed portion Nil as shown in Fig. 4 I which cooperates with portion94 of member 92. At the end of arm I02 of lever 97 is rigidly carried avertically extending member )3 the upper end of which is provided (inthe present embodiment) with an open-ended slot adapted to engage a pinI04 carried by escapement lever 62.

Function lever 45 is provided with a horizontal portion-I05 so conformedthat its extremity Hi6 engages the lower edge of arm Hi2 of lever 91!such that when function lever 45 is permitted to rotate in a clockwisedirection under the action of its spring 48 upon the proper setting ofthe vanes I07 in response to the tabulation code sig nal, the end I06thereof is elevated, causing lever 9 to rotate slightly in a clockwisedirection against the tension of its spring I08. The end lili of arm 96is thus moved downwardly, clear of portion 94, thus permitting spring 95to urge the tabulator bar 8i inwardly (or toward the left as viewed inFig. 3) until wall I09 of member 92 engages lug Hill. The series ofadjustable stops 96 are thus moved inwardly into the path of a cammember ill pivoted at M2 on a portion H3 integrally formed on a bar H5which is comparable to bar 53 shown in Fig. 1 of Patent No. 1,904,164employed for retaining the bell crank levers It in operable relation tovanes I07. Thus cam ill, like bar [l5 and bell cranks I3, is movablewith the type carriage l5 for character spacing. Cam 0 i i normallytends to rotate in a clockwise direction about pivot H2 due to theaction of spring i it, but its clockwise rotation is limited by thecoaction of a stop pin ill, carried thereon, with the end of bar H5.Thus, upon the rightward movement of type carriage l5, cam lill, due toits non-rotatability in a clockwise direction, will, by its cammingaction on any stop member 86, actuate tabulator bar 8! outwardly; butupon the leftward movement of type carriage l5, cam iii if striking anyof the series of stop members 86 will be rotated counterclockwiseagainst the action of spring H9 sufiiciently to pass the cam portion 89.

Upon the clockwise rotation of lever 9i due to the selection of functionlever 45, arm H02 and consequently portion we carried thereon will beraised and in so doing will, through pin Mi l, lift escapement lever 52out of engagement with the teeth of the ratchet 52 which, since thelever 53 is prevented from engaging the teeth of the ratchet 52 due toits being held in inoperative position by lever 65, permits the Wormgear to make one complete revolution instead of one-third of arevolution during the time that the main shaft rotates through onerevolution, and therefore the carriage will be spaced continuously adistance per revolution of the main shaft which is three times that ofnormal spacing so long as'the escapement lever 52 is held out ofoperative engagement with ratchet 52, which, as we have seen, ismaintained in this position due to the engagement of lug ill! with theunder side of step portion 941. Thus carriage l5 will be movedcontinuously until cam M l cooperates with one of the series of stops86, when cam ill through stop 86 will urge tabulator bar 9i outwardly,as viewed in Fig. 6 (or in a clockwise direction as viewed in Fig. 3),the effect of which is to disengage lug Bill from portion 94, whereuponlever 97! will again be rotated in a counterclockwise direction by itsspring 198 into the position shown in Fig. 3, in which event portion I93carried on arm H12 of lever 9'1 will again be lowered, permittingescapement lever 52 under action of spring 65 to engage one of the teeth6|, 6Ia, or Gib of the ratchet 52.

The function lever 45, however, will have been returned to itsnon-selective position, as shown in Fig. 3, at the completion of thefirst revolution or cycle of operation of the main shaft 2! by thereturn stroke or upward movement of shaft 50, where the lever 45 will beheld inoperative until the reception of another tabulation code signal,pursuant to which the foregoing cycle of operations will again occur.
